remove double osdep definition for gpsd an libxmu
convert to the new master/stable scheme
move drivers/velodyne_lidar in stable

It is required by the drivers/orogen/graph_slam package in rock1408
synchronize with rock1408

 - sbpl was never defined on master, only on rock1408
 - released software coming from outside rock has been put to stable
   when the version numbers show that it is released software (i.e. > 1.0)
